If your Logitech K850 wireless keyboard has stopped responding, won’t connect, or keeps disconnecting from your computer, you might need to reset it. The Logitech K850 is a multi-device Bluetooth keyboard that can connect to up to three devices — but when its memory or pairing settings get mixed up, resetting it can quickly solve most issues.
This guide will walk you through how to reset your Logitech K850 keyboard, reconnect it to your devices, and fix the most common pairing or performance problems.
Why You Might Need to Reset the Logitech K850
Over time, Bluetooth pairings can become corrupted, or the keyboard may fail to recognize one of your devices. You may also notice delayed response, missed keystrokes, or the keyboard not switching between devices.
A factory reset helps by clearing all saved connections and restoring the keyboard’s original settings. After resetting, you can easily reconnect it using either Bluetooth or the Logitech Unifying Receiver.
Step-by-Step: How to Reset Your Logitech K850 Keyboard
- Turn off the keyboard using the power switch on the top edge.
- Press and hold one of the Easy-Switch keys (1, 2, or 3) for at least 5 seconds until the light above it blinks rapidly. This removes the pairing memory for that specific channel.
- Turn the keyboard back on.
- Re-pair your keyboard:
- On Windows, open Bluetooth settings → “Add device” → select Logitech K850.
- On Mac, go to System Settings → Bluetooth → pair Logitech K850.
- On mobile or tablet, enable Bluetooth and choose the K850 from available devices.
- The LED light will stay solid briefly once connected, confirming successful pairing.
Reconnecting the K850 to Multiple Devices
One of the best features of the Logitech K850 is its multi-device connectivity. You can connect it to your desktop, laptop, and tablet all at once.
If switching between devices isn’t working:
- Hold down the Easy-Switch button (1, 2, or 3) until the LED flashes to enter pairing mode.
- Remove old pairings from the device’s Bluetooth list before re-adding.
- Use the Logitech Options+ app to manage connections and check for updates.
If your keyboard still won’t connect, consider testing your typing performance with a quick Keyboard Polling Rate Test to see if it’s responding properly.
Troubleshooting Common Logitech K850 Issues
If resetting doesn’t solve the problem, try these steps:
- Check the batteries – Low power can cause input delays or dropped connections.
- Use a different USB receiver port if you’re using the Unifying Receiver.
- Remove and re-pair the keyboard on all devices.
- Update drivers or firmware through Logitech Options+.
- Restart your computer after completing the reset.
If you want to confirm that all keys are working properly after reconnecting, you can test it using the Keyboard Counter tool. It shows how each key responds in real-time.
Resetting the Logitech K850 on Windows and macOS
- On Windows: Open Bluetooth & devices → select Logitech K850 → “Remove device” → add again.
- On macOS: Go to System Settings → Bluetooth → remove the keyboard, then re-pair it.
After pairing, make sure the keyboard layout matches your system language for accurate typing results.
Extra Tips to Keep Your K850 Running Smoothly
- Keep your Logitech Options+ software up to date for the latest firmware.
